KTP is the most widely used material for frequency doubling of Nd:YAG and other Nd-doped lasers, particularly when the power density is at a low or medium level,extra and intra cavity frequency doubled Nd: lasers using KTP have become a preferred pumping source for visible dye lasers and tunable Ti:Sapphire lasers as well as their amplifiers, it is also useful green sources for many research and industry applications.
